DxDesigner Source Schematic Files

I recently moved companies and my new employer just upgraded to Xpedition.

In previous DxDesinger versions the schematic source files were stored in ./SCH/, much like the symbol files that are still stored in ./SYM/. The visibility made it very easy to write scripts and use automation to reduce design time.

As so far as I can tell these files have been moved to some sort of database structure. Is there any way to still manipulate the source schematic files while not having to use the GUI?

You are correct that the schematics now reside in a database (the iCDB) but you can still manipulate the data via Automation. See the on-line help for details and also look through the Automation community for examples Automation and Scripting
